To design a swimming pool using stone tiles, one can start by choosing the type of stone tiles that are suitable for pool use, such as natural stone or porcelain tiles. Next, consider the color and texture of the tiles to create the desired aesthetic for the pool. It's important to ensure that the stone tiles are slip-resistant and can withstand exposure to water and chemicals. Additionally, the layout and pattern of the stone tiles should be carefully planned to create a visually appealing and functional design for the swimming pool. Finally, hiring a professional pool designer or contractor with experience in working with stone tiles can ensure that the pool is designed and installed properly. **

When designing the inner and outer border with a stone slab circle ring, it is important to first measure and mark the area where the ring will be placed. Then, carefully excavate the area to the appropriate depth, ensuring it is level and compacted. Next, lay a base of gravel or sand to provide a stable foundation for the stone slabs. Finally, carefully arrange the stone slabs in a circular pattern, making sure they are level and tightly fitted together. For the outer border, you can use larger stone slabs or bricks to create a defined edge and secure them in place with concrete or mortar. **
